Lobatus gigas, originally known as Strombus gigas, commonly known as the queen conch, is a species of large edible sea snail, a marine gastropod mollusc in the family of true conches, the Strombidae. This species is one of the largest molluscs native to the tropical northwestern Atlantic, from Bermuda to Brazil, reaching up to 35.2 centimetres (13.9 in) in shell length. L. gigas is closely related to the goliath conch, Lobatus goliath, a species endemic to Brazil, as well as the rooster conch, Lobatus gallus.

The queen conch is herbivorous and lives in seagrass beds, although its exact habitat varies by development stage. The adult animal has a very large, solid and heavy shell, with knob-like spines on the shoulder, a flared thick, outer lip and a characteristic pink-coloured aperture (opening). The flared lip is absent in younger specimens. The external anatomy of the soft parts of L. gigas is similar to that of other snails in its family; it has a long snout, two eyestalks with well-developed eyes, additional sensory tentacles, a strong foot and a corneous, sickle-shaped operculum.
